Stephen Colbert had promised to perform Rebecca Black's viral hit "Friday" on Late Night with Jimmy Fallon if the show's fans could raise $26,000 for the charity Donors Choose, and boy did he ever deliver. Colbert, Fallon, the Roots and a few surprise guests went all out for this performance, turning the much-mocked pop song into one of the most glorious and joyful things to air on television in recent memory. There's a lot to love in this clip, but the best thing about it is that everyone involved is celebrating the year's most absurd pop hit rather than making fun of the 13-year-old Black.
